Introduction to Pressure Balance:
In pipeline pressure testing, pressure testing is carried out after pipeline welding is completed. The pressure testing is mainly used to test the pressure resistance of the pipeline and whether there is micro leakage. The uncertainty, sensitivity, and high accuracy of the pressure balance cannot be replaced by any instrument at present, so the pressure balance is one of the indispensable instruments for pipeline pressure testing.
Characteristics of pressure balance:
The traditional pressure balance consists of a recorder and a pressure balance. The recorder is responsible for recording data, while the new pressure balance has an integrated structure with data exported via USB, which is convenient and easy.
Technical indicators of pressure balance:
Pressure range: (5~250) bar (10~500) bar or customized other ranges
Uncertainty: 0.05 level, 0.02 level, 0.01 level
Environmental monitoring: can display current humidity, temperature, and atmospheric pressure
Recording: Temperature and pressure can be recorded, and multiple temperature values can be recorded according to requirements
Highlight: Pressure balance is a precision instrument, and there should be no impurities between the piston rod and piston cylinder of the balance. Therefore, liquid static pressure balance is introduced on this principle, and the piston system is cleverly protected through pressure conversion.
